1%) which happened in the same period in 2019 (p = 0.004). Six of these patients were suffering from COVID-19. A total of 23,580 outpatients (93.8%) were cancelled. Emergency room consultations declined by 68.14% and 63.47% among white and green priority, respectively, while increased by 25% and 100% among yellow and red, respectively. Conclusion These numbers show the radical changed scenario in an orthopaedic center in Milan during COVID-19 pandemic. Elective surgery declined rapidly going close to zero, outpatient admissions were restricted to cases that cannot be postponed, while emergencies increased due to the role played by the hospital as referral orthopaedic centre during the pandemic. https://www.selleckchem.com/products/pf-9363-ctx-648.html The still ongoing emergency will have important impacts on the overall orthopaedic healthcare management for the next months.Purpose Periprosthetic joint infection (PJI) is a catastrophic complication after total joint arthroplasty (TJA). Treatment of PJI is challenging, especially when causative microorganism is not identified. The purpose of this systematic review was to guide diagnostic approach and treatment of culture-negative (CN) PJI. Methods A systematic review was undertaken on clinical studies from MEDLINE, EMBASE, Cochrane Library, and Scopus databases. Basic science studies, letters, studies written in languages other than English, case reports, and review articles were excluded. Results Proportion of CN PJI ranged from 5 to 42% of PJIs. Risk factors for culture negativity included prior use of antibiotic before culture test, inappropriate culture tools, insufficient culture period, and post-operative wound drainage. Specific diagnostic protocols including repeating sampling, longer incubation period, culture in blood culture bottles, sonication of implants, polymerase chain reaction in synovial fluid, and next-generation sequencing are recommended to identify undetected microorganisms. Vancomycin and cephalosporins are the most commonly used antibiotics. Two-stage revision arthroplasty showed success rate of 70-100%. Conclusions A comprehensive review was performed to provide an up-to-date, evidence-based guide to the management of CN PJI.Autoimmune syndrome induced by adjuvants (ASIA) is the spectrum of diseases in which the substances considered inert to the body induce autoimmune reactions and inflammation. Some of the biomaterials recently used in plastic surgery, such as silicone or polyacrylamide hydrogel (PAAG) seem to trigger clinical features of ASIA. The aim of this study was to assess the incidence of these features within a group of women after breast augmentation with PAAG. As many as 30 consecutive patients (26-59 years, mean age 39.5) referred to the Clinic of Plastic Surgery after breast enhancement with PAAG were examined. The validated criteria of ASIA syndrome were employed. Descriptive statistics were chosen based on the distribution of variables. The research was approved by the Bioethical Committee of the Centre of Postgraduate Medical Education in Warsaw, Poland. Within the studied group, 50% of patients (n = 15) fulfilled ASIA diagnostic criteria. Apart from local complications, we encountered various general symptoms, among which fever (n = 13, 43.3%), tingling and numbness of upper extremities (n = 10, 33.3%) and chronic fatigue (n = 9, 30%) were the most common. These symptoms were present on an ambulatory visit, before qualification to the operation of hydrogel removal. All patients undergoing surgical PAAG removal (n = 8) declared alleviation or complete resolution of the symptoms. Polyacrylamide hydrogel breast filling, although limiting the invasiveness of the procedure in relation to silicone breast implants, also carries the risk of developing ASIA symptoms. The removal of PAAG may bring improvement in some cases.The objective of this study was to compare rheumatoid arthritis (RA) disease activity and patient-reported outcomes (PROs) in a national sample of patients with RA with/without Sjögren's syndrome (SS). Adults with RA from a large observational US registry (Corrona RA) with known SS status between 22 April 2010 and 31 July 2018 and a visit 12 (± 3) months after index date were identified (n = 36,256/52,757). SS status determined from a yes/no variable reported at enrolment into the Corrona RA registry and follow-up visits. Index date date that SS status was recorded (yes/no). Patients received biologic or targeted synthetic disease-modifying antirheumatic drugs as part of standard care. Patients with RA only were followed for ? 12 months to confirm the absence of SS. Patients were frequency- and propensity-score matched (PSM) 11 and stratified by disease duration and treatment response-associated variables, respectively. Clinical Disease Activity Index (CDAI) and PROs 12 months after index visit were compared in patients with and without SS. Baseline characteristics in 283 pairs of PSM patients were balanced. Mean change in CDAI score was numerically lower in patients with RA and SS than patients with RA only (8.8 vs 9.3). Reductions in PROs of pain, fatigue and stiffness were two- to threefold lower for patients with RA and SS versus RA only. Reductions in RA disease activity and RA-related PROs were lower in patients with RA and SS versus those with RA only. Our data indicate that SS adds to treatment challenges; physicians may wish to consider SS status when managing patients with RA.Background Insufficient vascularization hampers bone tissue engineering strategies for reconstructing large bone defects. Delivery of prolyl-hydroxylase inhibitors (PHIs) is an interesting approach to upregulate vascular endothelial growth factor (VEGF) by mimicking hypoxic stabilization of hypoxia-inducible factor-1alpha (HIF-1α). This study assessed two PHIs dimethyloxalylglycine (DMOG) and baicalein for their effects on human adipose tissue-derived mesenchymal stem/stromal cells (AT-MSCs). Methods Isolated AT-MSCs were characterized and treated with PHIs to assess the cellular proliferation response. Immunostaining and western-blots served to verify the HIF-1α stabilization response. The optimized concentrations for long-term treatment were tested for their effects on the cell cycle, apoptosis, cytokine secretion, and osteogenic differentiation of AT-MSCs. Gene expression levels were evaluated for alkaline phosphatase (ALPL), bone morphogenetic protein 2 (BMP2), runt-related transcription factor 2 (RUNX2), vascular endothelial growth factor A (VEGFA), secreted phosphoprotein 1 (SPP1), and collagen type I alpha 1 (COL1A1).
